Nikki Hamblin of New Zealand stops running during the Women's 5000m Round 1 race to help fellow competitor Abbey D'Agostino of the USA after they collided. D'Agostino stopped her race, shook Hamblin's shoulder and said "Get up, get up, we have to finish this." Both runners, who had never met before, went on to finish.
